摘要：A voltage source converter has director valve phase legs in parallel withwaveshaper phase legs between two DC terminals. The director valve and waveshaperphase legs include upper and lower phase arms alternately operated to form
waveshapes on AC terminals of the converter, thereby allowing a number of waveshaperphase arms to be available for use for other purposes. At least one of the available phasearms is controlled to contribute to other aspects of converter operation thanwaveshaping.
